我有多个对象保存在arraylist中，arraylist保存在gson字符串中

我更改了对象的类（以包含更多变量和getter/setter方法）

现在，我在尝试加载旧对象时遇到错误（保存在步骤1中）

需要考虑的事项：

    public void loadDataSavedMatches() {
    SharedPreferences prefs = getSharedPreferences(SHARED_PREFS_FILE, Context.MODE_PRIVATE);
    Gson gson = new Gson();
    String json = prefs.getString("task list", null);
    Type type = new TypeToken<ArrayList<TennisMatch>>() {
    }.getType();
    mTennisMatches = gson.fromJson(json, type);

    if (mTennisMatches == null) {
        mTennisMatches = new ArrayList<>();
    }

    Log.i("LOAD DATA", String.valueOf(mTennisMatches));
    Log.i("LOAD DATA2", String.valueOf(prefs));

    //hashMap


    SharedPreferences hashPrefs = getSharedPreferences(HASH_MAP_SHARED_PREFS_FILE, Context.MODE_PRIVATE);
    Gson hashGson = new Gson();
    String hashJson = hashPrefs.getString("hashString", null);
    Type hashType = new TypeToken<HashMap<String, TennisMatch>>() {
    }.getType();
    item_map = hashGson.fromJson(hashJson, hashType);

    if (item_map == null) {
        item_map = new HashMap<String, TennisMatch>();
    }

}

我使用gson/json将arraylist存储在android共享首选项中。（共享首选项适用于其他值，错误出现在使用json/gson将字符串转换为arraylist时）

我的代码：

    public void loadDataSavedMatches() {
    SharedPreferences prefs = getSharedPreferences(SHARED_PREFS_FILE, Context.MODE_PRIVATE);
    Gson gson = new Gson();
    String json = prefs.getString("task list", null);
    Type type = new TypeToken<ArrayList<TennisMatch>>() {
    }.getType();
    mTennisMatches = gson.fromJson(json, type);

    if (mTennisMatches == null) {
        mTennisMatches = new ArrayList<>();
    }

    Log.i("LOAD DATA", String.valueOf(mTennisMatches));
    Log.i("LOAD DATA2", String.valueOf(prefs));

    //hashMap


    SharedPreferences hashPrefs = getSharedPreferences(HASH_MAP_SHARED_PREFS_FILE, Context.MODE_PRIVATE);
    Gson hashGson = new Gson();
    String hashJson = hashPrefs.getString("hashString", null);
    Type hashType = new TypeToken<HashMap<String, TennisMatch>>() {
    }.getType();
    item_map = hashGson.fromJson(hashJson, hashType);

    if (item_map == null) {
        item_map = new HashMap<String, TennisMatch>();
    }

}
